Seeing all of them would be wonderful. I'm personally hoping Luka gets made because she lacks scale figures aside from the Max Factory one (aside from Kaito and Meiko, but Stronger's got them covered here :D)

If ever they make Len, I hope they make the accessories on his hair a combination of translucent and transparent. and his hair should also fade a little. and I hope his cornea is made of clear blue glass.. A girl could hope xD
